We always like to do a roundup of reviews of new products from Apple. This time around it's one for their latest and greatest operating system, Mountain Lion. So down below you'll find reviews from Macworld, Ars Technica, Engadget, The Verge, Daring Fireball and more. And please sound off in the forums with your own review of Mountain Lion. Let us know what you think about the new cat in town.

Ars Technica - "Last year, I noted that despite its king-of-the-jungle name, Lion was not the endpoint of a decade of Mac OS X development; it was the start of a new journey. Mountain Lion makes the eventual destination a bit more clear," writes John Siracusa.

Macworld - "All told, I found Mountain Lion to be a stable, solid release. Even prerelease builds were far more stable than I've come to expect from OS X betas, leading me to wonder if Apple's new annual schedule is leading to more careful incremental updates (with fewer bugs) rather than great leaps (with more, nastier bugs)," writes Jason Snell.

The Verge – "Ultimately, this is pretty easy: you should spend the $20 and upgrade to Mountain Lion, especially if you have a newer Mac. You'll gain a handful of must-have features, and everything will get faster and smoother. I haven't really missed Snow Leopard at all since upgrading, which is remarkable considering how much I disliked Lion," writes Nilay Patel.

Engadget - "Does Mountain Lion justify its $20 price tag? Yes. Of course it does. If you're an OS X user with a reasonably new piece of hardware, stop what you're doing and upgrade now. There are 200 features here -- odds are you're going to discover a couple you like," writes Brian Heater.

Daring Fireball - "Mountain Lion isn't billed as a blockbuster release, and it isn't priced like one. It's just nicer. And it's the little things, the attention to detail, that show it best," writes John Gruber.

CNET - "Though it's not a complete system or interface overhaul, Mountain Lion's improved core apps and new features make it well worth the $19.99 price," writes Jason Parker.

PC Magazine - "Once again, OS X takes the prize as the world's best consumer operating system money can buy, and it looks well positioned to hold off the challenge of Windows 8," writes Edward Mendelson.

The Loop - "Mountain Lion costs $19.99 and comes with more than 200 new features - that's a bargain at twice the price," writes Jim Dalrymple.

Gizmodo – "It feels like Apple has run out of ideas. Or worse, that Apple is too afraid to implement new concepts, fearing it will kill the company's golden goose. Too afraid to change the world once again, as Steve Jobs used to say, one desktop at a time," writes Jesus Diaz.

Tech Crunch – "It must be said that Mountain Lion isn't really all that different from Lion - hence, the variation of the name (even though mountain lions are technically cougars - insert joke here). But unlike the jump from Leopard to Snow Leopard, which focused on performance and tightening code rather than features, the jump from Lion to Mountain Lion does pack some new goodies," writes MG Siegler.

AllThingsD – "For people who already use iPhones, iPads or iPod touches, many of the new features in Mountain Lion will feel like second nature. I can't completely rely on Notification Center just yet, but this operating system's focus on smart sharing and overall integration with social networks makes it a pleasure to use," writes Katherine Boehret.

ComputerWorld – "For users with production-critical machines, it may make sense to delay upgrades for a bit. For most users, however, there's no real reason not to take the plunge. Certainly, pricing shouldn't be an issue; this is the cheapest OS X update ever," writes Michael deAgonia.

SlashGear – "Apple's obvious competition is Windows 8, due to arrive in a few months time. Microsoft takes a different approach with its desktop platform, but from what we've seen so far it lacks the comprehensively integrated ecosystem that Apple delivers. iCloud is the glue that makes iPhone, iPad and, now with Mountain Lion, Mac, each act as an extension of the same holistic whole. If you love your Mac, OS X Mountain Lion is a no-brainer upgrade," writes Vincent Nguyen.

USA Today – "Apple has committed to a roughly once-a-year upgrade path with OS X, so don't be surprised if next year, Mac software resembles iOS software that much more. In the meantime, Mountain Lion is one big cat that you'll want on your computer," writes Edward Baig.

NY Times - "Over all, then, Mountain Lion is a gentle, thoughtful upgrade. All 200 new features? No, not really. But 10 that you'll use every day? For $20? Yes," writes David Pogue.
